Intelligent non-contact infrared electronic thermometer with voice broadcast

The program is written in C language and contains MLX90614 temperature measurement, OLED driver, and 4004-8 voice chip driver. The entire system is user-friendly. The user can choose voice broadcast or OLED display, low temperature or over-temperature alarm, and forehead skin function. Conversion formula from temperature to real body temperature (the formula has been verified by actual measurements and has high accuracy). The entire system has been verified to be feasible, and the measurement results were compared with electronic thermometers on the market, with an accuracy higher than 98%.
